If my "Save Incomplete Files In Folder" is on an internal hard disk and the "Destination" folder is on a hard disk attached to the router across the house from there I have noticed the following behavior. When I have multiple files being downloading in Transmission and a multi GB file finishes downloading the download speed of Transmission drops to zero while the completed file is copied from the internal hard disk to the disk attached to the router. The downloads then resume after the file has been transferred.

I assume that if the Incomplete Folder and the Destination" folder were on the same networked drive that the copy from one folder to the other on the same drive would be close to instant after completion of a download.

My question is: what are the performance considerations when the both file folders are on a networked drive?
